PRESS FOR MAKING BUTTONS.

To all 207mm it may concern Be it known that I, ALBERT C. LAUESEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Presses for Making Buttons, of which the following is a specification.

My invention relates to improvements in the type of presses for making buttons, or the like, which involve a pair of stationarily-supported die-members and a reciprocating die-member formed of relatively movable members and oscillatorily mounted to be swung into a position wherein it eX- tends above either-of the stationarily-supported die-members for cooperation therewith successively when depressed, in assembling and clenching together the elements forming the button, and in which means are provided for controlling the movement of the relatively movable parts of said reciprocatory die-member when cooperating with but one of the pair of stationarily-supported die-members for a purpose well understood in the art; and my object is to provide a novel, simple and improved construction of said last referred to means, and one whereby wear of the machine is minimized.

Referring to the accompanying drawings-Figure 1 is a view in side elevation of a press constructed in accordance with my invention, the reciprocatory die-member being shown as extending directly above one of the pair of stationarily-supported dicmembers in position to cooperate therewith, and said reciprocatory die-member in position to cooperate with my improved stopmeans; and Fig. 2 a view in front elevation of the press showing the reciprocatory die swung to a position in which it superposes the other one of said pair of dies and is in position to cooperate therewith. The reciprocatory die-member of the press is represented at 3, and as shown is formed of a rod-section 4 and a sleeve-section 5 vertically slidable 011 the lower end of the rod 4, as is usual in constructions of this type. The rod-section 4 is slidably supported in spaced bearings 6 on a frame 7 pivoted in a vertical plane on a rod 8 extending upwardly from the base 9 of the press, aspring 4? encircling the rod 1 and confined between the lower one of the bearings 6, and a stop-pin 10 on the rod 4: tend- Specification of Letters Patent.

ing to hold the die-member 3 in elevated position. A lever 11 provided with a cam 12 for engagement with the upper end of the rod 4: to depress the latter, is pivoted on the frame 7, as indicated at 13.

The parts 4 and 5 of the die-member 3 are provided for cooperation, successively, with a pair of die-me1nbers let and 15 stationarily-supported on the base 9, these diemembers being of a common and well known construction.

In the operation of a press of the type illustrated, the parts 4: and 5 of the diemember 3 are held, in a predetermined position, against movement relative to each other when the die 3 is cooperating with the die 14 in the first step of the button-forming operation, but in the last step of the button-forming operation the part 5 is free to yield to a greater extent when cooperating with the. die 14, all as is well understood in the art. My improved means for thus controlling the movement of the part a relative to the sleeve 5 comprises a latch 16 slidably and oscillatorily mounted on a rod 17 supported on the base 9, and PI'OVlClGxl with'a finger 16 which is adapted to enter the space between the sleeve 5 and a coliar 18 on the rod-section 4; when the reciprocatory die 3 is in the position represented in Fig. l, viz., in position to cooperate with the die-member 14. A spiral spring 19 surrounds the rod 17 and is confined between the base 9 and the lower end of the latch 16, the upper free end of'this spring being connected with the latch. A head 20 is fixed on the upper end of the rod 17 and carries a depending pin 21. The spring 19 is so compressed and tensioned that it normally holds the latch 16 up against the head 20 and the finger 16 of the latch against the stop-pin 21, so that the latch may be both moved down and oscillated against the tension of the spring 19, the latter serving to return the latch to the position illustrated in Fig. 2 when the reciprocatory die 3 is moved out of engagement therewith, the finger 16 being so positioned that it will normally oppose the space between the sleeve 5 and collar 18, whereby it will enter this space when the die-member 3 is swung over to the position illustrated in Fig. 1, the engagement of the finger 16 with the stop-pin 21 serving to prevent the finger 16 from extending into the space between the sleeve 5 and collar 18 when thedie-member 3 is itself to dies of different diameters when such are used, which is of importance in machines of this type. Furthermore, it will be noted that by constructing a press in accordance with my invention the use of mechanical means for disengaging the latch from the reciprocatory die-member is avoided, which is of advantage, as the wear on the machine is thereby greatly reduced and the liability of the machine becoming impaired for use is greatly minimized.

What I claim as new and desire to secure by Letters Patent is 1. In a machine of the character set forth, 'the combination of a pair of die-members stationarily supported on the base of the machine, a reciprocatory die-member adapted to be moved laterally into and out of registration with the die-members of said pair and formed of relatively movable members, a reciprocable and oscillatory latchdevice ivoted on said'base and engageable by said reciprocable die when in position to cooperate with one of said pair of dies for limiting the movement of one of said members relative to the other thereof, means tending to turn said latch, and a stationary stop cooperating with said latch for limiting the turning movement of the latter, for the purpose set forth.

2. In a machine of the character set forth, the combination of a pair of die-members stationarily supported on the base of the machine, a reciprocatory die-member adapted to be moved laterally into and out of registration with the die-members of said pair and formed of relat1vely movablemeirr,
